Thanks for the feedback including the PMs. At present it's hypothetical but just wondering how much trouble and expense it is.
I do like tinkering - but it becomes stressful when done away from home. There's always a tool that one forgets, or some unforseen complication that one would wish to sleep on before proceeding.
The other issue is that I don't drive, though my sister has a LGV license and could probably be persuaded to help.
